Performance Work Statement (PWS) 13.8-4160 Transformer-Disconnect Repair Adelphi, MD Army Research Laboratory – Sensors and Electron Devices Directorate

C.1 BACKGROUND:

This PWS outlines the repair of an existing concrete pad mounted, 60 Hertz (Hz), 13,800 Volts Alternating Current (VAC) to 4160 VAC Delta-Wye, 3000 Kilo Volt Amp (kVA), ASEA Brown Boveri (ABB) unit substation that is used at the Power Electronics facility in building 500 at the Army Research Laboratory, Adelphi Laboratory Center (ALC), Adelphi MD 20783. The 13,800 VAC VersaSwitch on the high side of the transformer was severely damaged due to an animal induced flash over event across two (2) of the three (3) phases. The event damaged multiple fiberglass interphase barriers, busbar assemblies, 18 kilovolt (kV) surge arrestors, A155C2D0R0-125E fuses, porcelain standoff insulators and cables in the VersaSwitch Cabinet. The three (3) phase, type Restricted Substance List (RSL), oil insulated unit substation transformer’s primary to secondary windings was tested and deemed to meet industry standards and does not require repair. The Medium-Voltage Vacuum Power Circuit breaker contained in the 4160 VAC cabinet was inspected and found to be exposed to rodent activity and will therefore require testing and a maintenance action to ensure proper operation. The existing service in the manhole is a wye splice from the 500 thousands circular mils kcmil, 15 kV, Ethylene Propylene Rubber (EPR), 133% insulation level, single conductor service (feeder 1-7) with a 3/0 copper ground wire. The existing tap is terminated in live end caps. The Period of Performance (PoP) for this requirement is anticipated to be three (3) months after contract award and two (2) option years.
